Product Description:
The Danfoss 131B6688 is an HVAC Drive. It refers to model FC-102P1K5T4E55H1XGX1XXSXXXXAXBXCXXXXDX. This unit delivers 1.5 kW rated power with a typical shaft output of 2.0 HP at 460 V.
The 131B6688 belongs to the series of VLT FC 102 HVAC Drive. It works with 3×380–480 V AC mains supply. It supports frequency ranges of 50 or 60 Hz with ±5 % tolerance. Output voltage is adjustable from 0 to 100 % of supply. The output frequency range is 0 to 590 Hz with ramp times adjustable from 1 to 3600 s. Efficiency reaches 97 % with a power factor of 0.98. Short circuit rating is 100 kA when fused correctly. Continuous output current is 4.1 A at 380–440 V and 3.4 A at 441–480 V. Intermittent overload current for 60 seconds is 4.5 A and 3.7 A in respective voltage ranges. Apparent power is 2.8 kVA at 400 V and 2.7 kVA at 460 V. Maximum input current is 3.7 A with 4.1 A peak at 380–440 V. At 441–480 V it is 3.1 A with 3.4 A peak. Typical power loss is measured at 62 W. Control features include four digital inputs expandable to six with PNP or NPN logic and up to 110 kHz pulse frequency. Two analog inputs allow ±10 V or 0–20 mA with 10-bit resolution. One analog output supports 0–20 mA signals with 12-bit accuracy. Two digital outputs handle up to 32 kHz with 40 mA current. Two relay outputs are rated for 240 V AC at 2 A.
The 131B6688 drive operates from 0 °C to 50 °C with storage down to −25 °C. Torque capacity allows 110 % overload for one minute and up to 135 % starting torque for 0.5 seconds. Motor cable length supports 150 m screened or 300 m unscreened. Maximum cable sizes are 4 mm² with disconnect option at 6 mm² for mains. It works reliably at 5–93 % humidity and altitude up to 1000 m.
Frequently Asked Questions about 131B6688:
Q: Why does the 131B6688 Drive require 100 mm airflow clearance?
A: Adequate clearance maintains cooling efficiency of the enclosure. It prevents overheating and supports consistent drive operation.
Q: How do digital inputs with 110 kHz pulse capability benefit HVAC?
A: They enable high-speed signal processing. This allows precise control of fast-responding actuators.
Q: Why is galvanic isolation important for the RS-485 in Danfoss drives?
A: It separates control circuits from power circuits. This protects sensitive electronics from voltage disturbances.
Q: How do the internal +10 V and +24 V supplies support the 131B6688 Drive?
A: They provide stable reference power for sensors and control devices. This reduces the need for external supply sources.
Q: What role does the PKZM0-25 breaker play with the 131B6688 Drive?
A: It provides safe disconnection under fault conditions. This protects both the drive and connected motor equipment.
